Application filed August 22, 1908. Serial No. 449,336.

To all whom it may concern:

Be it known that I, SAMUEL N. KRAW- cnnnno, a citizen of the United States, residing at Wilmington, county of Newcastle, and State of Delaware, have invented a certain new and useful Improvement in Loadcrs, of which the following is a specification.

My invention relates to a new and useful improvement in loaders and especially to that class of loaders which are used in conveying coal, sand, stone and the like from one ship to another, from a ship to the dock or vice versa or from one place to another on land, and has for its object to provide an exceedingly simple and effective device of this character whereby articles may be conveyed from one point to another, through tube thus preventing loss.

Another object of my invention is to provide a loader with a revolving screw thus drawing the coal, sand or other articles through a tube at a continuous rate of speed.

Another object of my invention is to provide a loader the receivin end of Which may be moved about from p ace to place.

A still further object of my invention is to provide a loader composed of a number of sections so that said sections may be taken apart enablin the loader to be stored away in a very sma 1 space.

Another object is to construct a loader which may be made longer or shorter as the case ma be so as to reach from one vessel to anot er although said vessels may be tied close together at one time and far apart at another.

Another object of my invention is to provide a loader which will be flexible.

. My loader may be used in the construction of tunnels andthe like thus doing away with the use of wheel-barrows as a receiving section might be placed at either end of the tubingand by running the engine in one direction the dirt could becarried out and then by reversing it. the construction terials could be carried into the tunnel \Vith these ends in view this, inv consists in the details of construction and combination of elements hereinafter setforth and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, I will describe its construction in detail, referring by letter to the accompanying drawing forming a part of. this specification, in which Figure 1 is a plan view of a portion of two vessels showing my improved loader in use. Fi 2 is a side elevation; Fig. 3, a longitudinal sectional view of the receiving end of the tube showing one section of the revolving screw in elevation. Fig. i, an end view thereof. Fig. 5, a side elevation of the meeting ends of two sections of the revolving screw. Fig. 6, a longitudinal sectional view of one of the sections of tubing, the revolving screw being removed. Fig. 7, an edge View of one of the rolls on which the tubing is adapted to rest. Fig. 8, a side elevation thereof. Fig. 9, an end View of the horse on which the end sectionsof the tubing rest when in operation, and Fig. 10, a side elevation thereof.

In carrying out my invention as here embodied, A and B represent two ships tied to one another a short distance apart, the ship A being the one which is tofreceive the material andthe ship 13 the one carrying the material which is to be loaded into the ship A.

C denotes the loadercomposed of a number of sections D each of said sections being formed of stri s of metal 'E overlapplng one another so t at said section will be flexible. About these metal strips is then placed a canvas or other suitable covering F for holding the metal parts securely together. To one end of each of the sections D is secured the male coupling member G on the outside surface near the inner edge of which are formed the threads H but said threads do not extend around the whole periphery of said coupling, on the opposite end of each of the sections D is attached the female coupling 1 having lugs 1 formed therewith on the inner surface of wh1ch are formed the threads J.

lnplacing the sections together themale coupling G of one of the sections is placed in the female coupling I of another section and by turningthe sections the threads H Wlll engage with the threads J thus securely holding said sections together. A set screw I may he threaded into one of the lugs on each female coupling member which will jam against the male coupling member when in position which will assist in retaining the couplings in place. To one of the end sections is then secured the receiving member K which is formed similar to the sections l) except that one end is cut on an angle as indicated by L, and in this end is placed the bracket M in which is journaled one end /of one of the revolving screw sections N which is composed of a shaft 0 and a flange P, said flange extending from the shaft to the inner surface of, the tubing. To the opposite end of the screw section N is detachably secured one of the other screw sections Q, which is formed similar to the section N in as much. as it has a shaft R and a flange S, one end of said shaft R has a slot T formed therein, the sides of which diverging from the inner to the outer extremities of said slot, and in this end is also formed a hole U for the reception of a bolt. The opposite end of the shaft R is formed with the tongue V at right angles to the slot .T, the sides of which diverge from the outer to the inner extremities thereof, and in this is formed an elongated opening W for the reception of the bolt which passes through the hole U, thus it will be seen that when these sections are brought together and the bolt placed through the shafts the sides being formed at angles, and the opening W being elongated will allow said sections to move back and forth at this point thus producing a flexible joint. These revolving screw sections run throu h the tubing to the end which is place on the ship being loaded at which point the axle of the end screw section is detachably secured to the engine Y so that when the engine is in motion it will cause the screw sections to revolve thus forcing the material which is placed in the receiving section through the tubing to the opposite end thereof at which place the section is provided with an opening Z' through which the material passes into the hole A leading to the hold of the vessel. The receiving section K is provided with swiveled wheels B so that said section may be readily moved about from place to place.

The rolls C have a gI'OOVG'fOID'IBd 'on their periphery as indicated by D in which that part of the tubing between the ships is adapted to rest sothat it will be prevented from swagging down or breaking on account of its weight. Through the center of these rolls is formed an opening E through which is adapted to pass the rope F the ends of which, are fastened to the masts of the vessel,'thus holding the rolls and allowing them to move downward as the ships move closer together, and to pull the rolls up when the ships move apart. A rope G also passes through the opening it, the ends being secured to the cleats or other suitable places on the ves el along side of the one to which the rope F is secured, which will keep the rolls C in the position desired.

H represents a horse the hac or which has a curved opening I in whic .a of the tubing on either ship is We,

I rest in this way holding s'aid tubing in one position while being used. When used for loading ships the receiving end of the tub ing is placed in the hold of'the ship from which the material is being loaded or on the dock proximity to the coal pile, the opposite end being placedover the hole leading to the hold ofthe ship to be loaded. The material is then shoveled into the receiving end and the revolving screw being in motion will force the material through the tube to the opposite end thereof from where it will be discharged in the hold of the ship. As shown in Fig. 1 the engine may have secured to it two leaders one to either side thereof leading from two different ships or places into the one ship being loaded thus facilitating and shortening the time of loading a ship with coal.

Of course I do not wish to be limited to the exact'details of construction here shown as these may be varied within certain limits without departing from the spirit of my invention.

Having thus fully described my invention, what- I claim as new and useful, is-

1. In a loader, the combination of atubing formed of a number of sections detachably secured together, one of the end sections being the receiving member having one of its ends cut on anangle, a bracket fastened tosaid receiving section in proximity to one end thereof,,a revolving screw section one end journaled in said bracket, the opposite end section having an elongated opening formed inthe side thereof, said section adapted to rest above the hole in the hold of the ship to be loaded, revolving screw sect-ions detachably secured together and detachably secured to the section journaled in the receiving end of the tubing, and means for turning said revolving screw,'as specified.

2. In combination, a loader composed of a number of similar sections of tubing detachably secured together, a receiving section, one end of which is formed on an angle detachably secured to the other sections, a

' discharge section having an opening formed in the side thereof detachably secured to'the other sections, each of these sections of tubing being composed of strips of metal overlapping one another, and canvas or other suitable covering placed around the outside of said metal strips, a male and fen'iale coupling secured to the sections, a revolving screw composed of a number of sections, each section being formed to produce a shaft and a flange thereon, one end of said shaft being provided with a slot the sides of which diverge-toward the end of the shaft and an opening passing through said end, the opposite end of said shaft beprovided with a tongue the sides of which diverge from the outer toward the inner ends of said tongue, said tongue having an elongated opening formed therein, means'for detachably securing said sections together, a bracket secured to the outer end v of the receiving section in which is journaled one end of one of the sections of the re-" volving screw, wheels swiveled to the receiving section of the tubing, means for detachably securing one end of the revolving screw to a power shaft, rolls having a groove formed in their periphery and openings passing through thecentral portion thereof,

'lneans for hanging said rolls from the ships allowing the tubing to rest in the groove portion thereof, and horses having a. curved opening in their backs on which that portion of the tubing which is above the shipis adapted to rest, as shown and described.

In a loader, a number of similar sections, of tubing' composed of strips of metal overlapping one another, canvas or other formed a short distance around the periphery thereof, said threads adapted to engage with the threads formed on the lugs, a re-' c'eiving section one end of which is formed on an angle detachably secured to the other sections, a discharge section having an opening formed in the side thereof adjustably secured to the other sections, a revolving screw composed of a number of sections each section being formed to produce a shaft and a flange thereon, one end of said shaft being provided with a slot the sides of;which diverge toward the end of the shaft and an opening passing through said end,'the opposite end of said shaft being provided with a tongue the sides of which diverge from the outer toward the inner ends of said tongue, said tongue having an elongated opening formed therein, means for detachably securing said sect-ions together, a bracket secured to the outer end of the receiving section in which is journaled one end of one of the sections of the revolving screw, wheels swiveledto the receiving section of the tubing,-

and means for turning the revolving screw, as shown-and d escribed.

In testimony whereof, I have hereunto aflixed my signature in the presence of two subscribing witnesses.
